Write the equation of the circle in standard form. then find the center x2 + y2 - 22x - 12y + 121 = 0

Standard form:

or

The center is and the radius is .

Step-by-step explanation:

We will group terms with together and also group terms with together.

We will not subtract 121 on both sides.

We are about to complete the square both both the terms and then the terms.

Whatever we add on one side, we must add to the other.

We can also write it as:

Now it it easy to compare to:

to find the center and the radius, .

The center is and the radius is .

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
